Abstract
The Canadian Light Source (CLS) storage ring has been operating routinely since commissioning was completed in the spring of 2004. Since that time the storage ring parameters have been adjusted in efforts to increase the brightness of the source. This includes changes to the operating point, reducing the transverse coupling and optimizing the dispersion at the source points. Depending on the photon energy brightness and flux from the undulators are increased by reducing the beam size or reducing the emittance. This is achieved with higher tunes which both decrease the emittance and the vertical beta-function while increasing the horizontal beta- function. Dispersion at the undulators can be optimized to minimize the beam emittance or beam size. Vertical coupling can be adjusted to less than 0.1% by reducing both the vertical dispersion and transverse coupling or increasing the vertical tune. The performance of the IR beamlines has been enhanced by producing coherent THz radiation from short bunch lengths.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
